Best way to get the "Losing My Marbles" achievement?

So I am playing my first game (Prince difficulty), and I want to see if I can shoot for the "Losing My Marbles" achievement.
Looking at my map, I can see three different ways of doing it:

1. Stealing 5 artifacts from the Inca, making them super angry at me;
2. Steal two artifacts from The Inca, two from Venice and one from Spain - making them angry at me, but they are all on another continent, and I have a strong navy;
3. Steal one artifact from each civilization, making all of them slightly annoyed at me.

Also, I am alone on an island, with only one city bordering America. I am planning on winning Diplomatic (so I want to play nice with civilizations), but I have Cultural and Scientific Victories as my plans B and C.

From those who already have some experience with the game, how should I go through this? How harsh is the penalty for stealing artifacts?
I am aware that, if I promise them to not steal from their cultural heritage, I cannot break that promise without severe repercussions...

Stealing once and promising not to do it again is a pretty minor hit

Being unrepetant or stealing a bunch of times will piss them off quite a bit, though if you're aching for a tumble anyway, might as well yank some of their goodies.

Looking back at my game, maybe pissing off Pachacuti isn't the best idea - he's my best trade partner (Trade Routes with him are delisciously profitable).
Though I was thinking of digging them up all at the same time to diminish his reaction (I suspect doing them all in the same turn I can then promise not to do it again and everything's fine).

If I can steal once with minor hits, then I might just go for all of them. My museums will be rich indeed!

As far as I'm aware, taking one artifact and never doing it again doesn't carry any diplomatic penalty, in my experience, though to be fair, I was stealing from my friends.

Yeah I was thinking of ways to get this achievement as well. It is probably one of the easier "tricky" ones to get though doing something like you said.

Though I am not quite sure on the reading. From the achievement wording, it seems like all 5 artifacts need to be from the same civ.

"It Belongs in a Museum" sounds like a pain in the ass though. Its hard enough to find any CS artifacts, but 10 of them? I'm thinking maybe a huge map is the best way for that, with A LOT of CS in the game.

Well, that would be a hurdle... Everyone just denounced The Inca (most probably because they proposed their religion for World Religion), so maybe pissing them off isn't that bad... Still, getting 5 artifacts from the same civilization makes for a hard achievement!
Well, I guess I will find out... No harm done if I don't get it - I still plan a Culture game as Brazil, and late game aggression is not that bad for them!

EDIT: It appears to be the case, unfortunately...
By now I already promised Pachacuti I would not steal anymore artifacts... Is this like the "I will not settle near you" promise? I mean, does it eventually run out and I may safely break it again?
If so, I might just wait and see if I can lay my hands... Oh wait... I have no more slots to place Artifacts... Well, I'll try it again on my Brazil game!
